I have both an android tablet and an iPhone but primarily use my iPhone or Macbook Pro.

Some file types are not supported when streaming on my iPhone such as *.mkv. In the android version, the app allows you to use VLC as the pass-through player so all videos are supported. I have seen other players that support this plugin and allowing the native player to decode the movies through the native app.

Can you please look into implementing a better media player/integrating better codecs?

A macOS app would also be much easier than using the WebAccess when remotely accessing the items.

Apple has their own file format you can't play any random file format. In fact, you need to convert videos into the working format before transferring the file to your iOS device. You can even watch movies on the Internet without downloading on your device. You can watch watch movies online (https://www.allstreamingsites.com/online-free-movie-streaming-sites/) on sites listed in the article.

Anyway, update that horrible app for ios to ios 12 iphone x. 2 years ago it is the last update. jesus! And olso add Dynamic DNS others then your buffalo nas. Because now is useless if you have another Dynamic DNS service.
